To all whom it may concern:

Be it known that I, HENRY R. FARMER, of Ringgold, in the county of Pittsylvania and State of Virginia, have invented a new and Improved Apparatus for Curing Tobacco, of which the following is a specification:

My invention consists ol' a heating attachment to barns or other buildings in which tobacco is stored for curing the tobacco by artiticial heat radiated directly from pipes made to conduct the heat about the lower part of the room from a furnace outside provided with regulating valves or gates, and in combination with a valve or register located directly over the hot-air pipes to so temper the heat at the entrance into the barn that the building Will Figure lis a horizontal section of my improved tobacco-curing apparatus, and Fig. 2 is a longitudinal sectional elevation of the apparatus taken on .line x m.

Similar letters of reference indica-te corresponding parts.

A is the furnace, which is preferably made a little tapering from the front to the back. B is a flue extending from the back of the furnace through the wall C of the tobacco barn or house, and connecting with the heatcirculating pipes D, Which are extended across the room in any approved Way for causing the best and most even circulation of heat and out at the other side to discharge into the atmosphere, and on the discharge ends of these pipes, Which turn upward in suitable manner, there is a cowl, E, for the protection of the draft, and to direct the discharge so as to protect the barn. J represents gates or dalnpers to regulate the heat, and over the furnace is a passage, K, for cold air, with a regulating damper or valve, L, to admit cold air, more or less, as may be required, for the protection of to regulate the temperature of a'curing-room in the manner described.
